Good point! Actually it took 2 days to NOT make a pot, all that came from the brick furnace was slag,, what wasn't shown here was the scraping of the cr*p out of the crucible and melting down some scrap iron to actually pour the pot. Took longer to clean the cr*p from the crucible than to melt the iron for the pot! Colin
When you consider that I had given a complete "run through" of how we would do this both for practical and saftey reasons not 5 mins. before, it was kind of unbelievable! I think my frustration ahhh. kind of showed! Colin
Normally there wouldn't be any dirt getting scraped in with the metal, but re-melting it in the furnace would turn it into floating slag. But since there was nothing usable in the pot anyway it didn't make a lot of difference. My web site address comes up at the end of the video, email me from the links on my site if you're interested in a book on building and using my waste oil furnace design, that's the one that works, not the brick one! Colin
That's correct, the term "green sand" doesn't refer to the colour of the sand but that it's used "green". Green meaning it's uncured, cement or concrete is in a "green state" when it's firming up but not yet cured. The clay content binds the sand together, too little clay and it will break up when the pattern's removed. Too much clay and it isn't porous enough to allow the gasses out. Also it can bake too hard from the hot metal and have no give which will cause the casting to crack as it cools
Thank you, I keep meaning to add some more casting videos, but I'm so busy with other projects I don't seem to get around to it! Hopefully soon. Best thing to so though is to get busy yourself, it's great fun. Colin
The producer wanted them to handle the entire pour including lifting the crucible, this is why I I handled that part. Still no animals or TT riders were hurt in the making of this film. Colin
Never open a flask right after pouring. It takes a bit of time for it to solidify. If they had opened the mold it would've ruined the casting and possibally got badly burned.
Your assertion that there are relatively few inventions that have truly been created in the US is absurd. The list that you are asking for would take up volumes rather than pages...which is also true for the UK as well. Many great innovations have been created all around the world. Genius doesn't have a nationality.
Ahhhhhh, but buying one off eBay didn't get you on TV did it? It also didn't boost the sales of your book on how to build the furnace that cast it? What the hell, it was good fun, enjoy your pot. Colin
Hi Rob, iron must be melted in a crucible, it cools down too quickly in the bottom, about all lower temp. metals will melt in the well and can be tapped. The furnace design allows for direct melting without a crucible, but unfortunately not for cast iron. The book is on eBay, if you tap "The Artful Bodger" in an eBay search you should find it. Alternatively email me from the links on my site which comes up at the end of my video clips. Colin
This one did creep and there was a lot of flash to grind off, it depends on how hot you get the iron to how fast it sets, Because we only had one chance with this (due to time restrictions), and I knew there would be a some messing around with the pour, I let that iron get very hot before lifting the pot. Colin
giday colin, do you sell your books on ebay and can you furnace be made to be like a cupola with tapping the melt, because I hate handling hot crucibles? thanks mate, rob
It's a clip from a TV program, I guess the producer thought "nothing wrong with a bit of drama". Personally I got a bit pissed off with the whole deal, guess I wasn't cut out for the small (or big) screen. Colin
It would be quicker if you listed what you lot had invented, and I mean factually correct inventions not what's printed in your unfactual history books!!!
Castings that thin freeze within 2 seconds but the sprue will still be a liquid. I know because I have done it myself thinking that a casting was a failure and knocked out the sand and to my suprise the casting had solidified in that short space of time.

I have my grandmother's, I certainly appreciate it more now after the detailed process of making such a treasured item.
When you consider that I had given a complete "run through" of how we would do this both for practical and saftey reasons not 5 mins. before, it was kind of unbelievable! I think my frustration ahhh. kind of showed!
Colin
Exactly! That was all slag anyway, this was a "make it look good for the camera" deal, Off camera I melted scrap iron which is what was poured.

This poor blacksmith had to do everything to fix and help these "boys"
where they really gonna break it open while it was still molten?
Oh well I'm hooked now. I have to see the rest. Very interesting show.
Ah...that's what you get when you have inexperienced sand crabs!
Grand job on the casting!
Wish you had more info on making the mold for the cauldron . How to make each part of the mold mostly the inside part of cauldron

I don't do "fancy wood work" but I've restored a few wooden boats. I also make bows, have a look at my wooden compound bow in my other videos.

That was cool!!
Four guys spent two days making a ten dollar pot. What branch of Goverment do you work for?

Colin
I always take a long spoon and slightly dig from the top of the mold to check for proper cooling.
Thank you
Colin
Great! But I think what found Jason Stathem!) )
I realized Guy Martin at the end and not realize Jason Statham until I read comments :))
Epic pot making.
Thank you, no you just can't get the staff these days!
Colin
Why would they have touched the mold so quickly after just pouring molten steel?!
Stupid?
Thanks
Colin
Wh0h000 dats qwoyt splendid dant ya rek em?
That's a potjie 👍
conguralations!
made my day !!!
Great!
Stalin as a metal expert?!
Yeah, he produces best metal in the world called stalinium (isn't that funnyn in English though... stal in Polish means steel)
Yes it is.
Colin
Is that Guy Martin!!!????
@paikmendez No its a term of affection when talking to your girlfriend or wife.
giday colin, do you sell your books on ebay and can you furnace be made to be like a cupola with tapping the melt, because I hate handling hot crucibles?
thanks mate,
rob
The boys put what!!!!!
Do you do iron casting for individuals? I have a wood stove damper that is broken, but could still be used for the mold. It is 25”L x4”w x 1/2” thick.
Sorry mate but I have too much on the go to take on outside projects
Colin
As long as I come off fine!!
Colin
Yes he's Guy Martin
Colin
2:41 its got to go out the spout
Stalin and jason statham cooking iron
The Boat That Guy Built
wanna see the rest
0:49 face look like guy martin indeed
the guy with the bread is he a TT isle of Man racer?
Amongst other things yes
what are you doing @guy martin: ) ?
thats guy martin? nice
Just poking a little fun back at ya!
Colin
Ohohhohoho!
Just green sand
Colin
I'm suprised the Ameri-cant's aren't on here claiming they invented green sand casting...
Politeness.
Colin
she´s comming that what he said
Why does she call these old men "the boys"
lmfao why is this presented so dramatically
It's a clip from a TV program, I guess the producer thought "nothing wrong with a bit of drama". Personally I got a bit pissed off with the whole deal, guess I wasn't cut out for the small (or big) screen.
Colin
Green sand means damp sand =facepalm=
Still learning.....
jon sanford A modern version of your father's video.
+Helena thanks
Jason statham ? haha
bad ending
ahahhahaahha
It would be quicker if you listed what you lot had invented, and I mean factually correct inventions not what's printed in your unfactual history books!!!
Thank you
Colin
Hey Colin, how did they made the mould for the inner hole?
Thanks
Sand and sodium silicate. Then apply CO2 and sand mix will harden. You have to break the sand away when done.
Thank you
Colin
Thank you

Hopefully I'll get around to a detailed video of making them soon, bit expensive to send you one!
Colin
Its not just wet sand in green sand there is also around 20 percent clay if I remember correctly.
Thank you.
Colin
